Thawing permafrost on various peatlands in Alaska.

Thawing Permafrost, Alaska

Thawing permafrost on various peatlands in Alaska. Permafrost thaw results in ground subsidence and inundation that kills black spruce and other understory plants living on the permafrost plateau. The black spruce forests found on permafrost plateaus are replaced with sedge- and moss-dominated bogs and fens, altering the ecosystem structure and function.
